Specification of Letters Patent.

rammed March 27, 1906.

Application filed September 9; 1904'. an to. 223.938.

Be it known that I, ESSE RENO, teat zen of the United States, residing in the borough of Manhattan, city, county, and State 'of New York, have invented a new and useful Apparatus for Lining Tunnels with 'Concrete, of whi oh the following is a specification;

My invention relates toimprovements in methods of and apparatus for the liningfof tunnel-tubes with concrete, its object being to carry on thework of applying such lining step by st'ep simultaneousl'y with the driving of the heading and to keep the lining work close to the heading and it' consists in the features of construction and method s of operation hereinafter particularly described and claimed.

' In the accompanying drawings, forming part of this specification, Figure 1 is a crosssection of a tunnel, showing the tube, the concrete lining in place therein, and my improved apparatus in working position. Fig.

2 is a smaller cross-section of the tube in finished condition, with the temporary framework and concreting center or shield removed. Fig. 3 is a longitudinal section of the tunnel, showing the temporary platform upon which the concreting operations are carried on, the shield in place thereupon, and

the bridges at each end of the platform for carrying the cars from the bottom of the tunnel onto the platform, and vice versa;- and Fig. 4 is a horizontal section of the tunnel and a plan view of the platformand tracks;

In the drawings, A- represents the tunneltube, made up of segments 2, having longitudinal flanges 3 and circumferential flanges 4.

IB is a temporary platform, arranged substantially in the plane of the horizontal diameter of the tunnel and made up of cross from the heading. At each end of the tem-.

porary platform is arranged a bridge C, upon which are arranged tracks 9, connecting with the rails of corresponding tracks 9 in the bottom of the tunnel. Upon the platform switches 22, 23, and 24 are also provided, as shown in Fig. 4, by means of which cars may be run from either of the tracks 9 onto the siding-tracks 10 on the platform, and from such sidings onto the main tracks at either end of the platform, as clearly shown in Fig. 4. Whilethe-cable 11 is shownin working relation With the tracks9, it is, obvious that it I could by proper guide-sheaves be carried from trucks 14, which carry jacks .15, supporting 'the stringers 16, upon which in turn rest the Arranged longitudinally of the platform B are also stringers 13, servingas tracks for thelongitudinal timbers 1 7 of the center D.

"This center is made up of the channel-iron cross-pieces- 18, struts 1-9, braces '20, and

covering-plates 2-1. The construction and method of using the center are disclosed and covered in my prior patent, N o. '7 61 ,786, dated June 7, 1904. The gist of this invention is 'a modification upon my other method and apparatus, as disclosed in said patent, 1

.whereby the through traffic of material-cars between entrance and heading is maintained along the bottom of the tunnel, excepting at the point where the lining operations are at the time being carried on, where such cars are carried over the bridges and platform.

The apparatus is operated as follows: The heading being driven far enou h to afiord suflicient s ace within the comp eted tube in the rear t ereof for concreting. purposes, a temporary platform B is erected, provided with tracks and the connecting bridges and tracks,- as above described. Material-cars are operated over the bridges and platform,

and the concreting operations conducted.

thereon until the arch and invert of the tunnel for the length of the platform has been lined. After this the bridges C are detached from the platform, and the rear sections or bents of the platform are transferred to the other end to extend the platform forward toward the heading, and tracks are laid upon the bottomof the completed part of the tunnel. The bridges are then connected to the platform'thus advanced and the foregoin -described operation repeated. Ordlnari y I prefer to operate the material-cars over the central tracks upon the platform. In some cases, however, it may be desirable to switch them from the middle tracks to the outside tracks, returning them to the middle tracks as they pass off from the platform onto the bridge. In either case the cars with concreting materials are brought in on the tracks leading from the entrance and set upon the tracks on the platform which are not required for the through trafiic.

I claim 1. In tunnel construction, means for carrying on simultaneously the several operations of driving the heading, erecting a tube in the bore, and lining said tube in the rear of the heading progressively as the heading advances, comprising a substantially diametric platform adjustably arranged at the point of lining operations, through-tracks thereover connecting entrance with heading for material-cars, and subsidiary tracks for concreting apparatus interconnecting with said through-tracks.

2. In tunnel construction, means for circumferentially and step by step lining the tube with concrete as the heading advances, comprising a temporary platform and approach-bridges adapted to be advanced with the progress of the work, through-tracks from entrance to heading passing over said bridges and platform, and subsidiary tracks upon said platform connecting with said throughtracks.

3. In tunnel construction, in combination with the tunnel-tube, a temporary diametric platform, removable bridges at each end thereof leading from the bottom of the tube to the platform, through tracks runnim along the bottom of the tube and over salt bridges and platform between entrance and heading, subsidiary parallel tracks on said platform, and switches interconnecting said subsidiary and through tracks.

4. In tunnel construction, in combination with the tunneltube, a substantially diametric platform adapted to be longitudinally adjusted therein, a removable bridge leading from each end of said platform to the bottom of the tunnel, main tracks along the bottom of the tunnel and over said bridges and platform, side tracks upon said platform, switches connectin the side tracks with the main tracks and concreting apparatus adjustably arranged on said platform.

In witness whereof I have hereunto set my hand, at the city of New York, this 7th day of September, 1904:.
